Agile development practices introduced, adopted and extended the XP-originated "User Story" as the primary currency for expressing application requirements within the agile enterprise. The just-in-time application of the user story simplified software development and eliminated the prior waterfall like practices of overly burdensome and overly constraining requirements specifications for agile teams.
However, as powerful as this innovative concept is, the user story by itself does not provide an adequate, nor sufficiently lean, construct for reasoning about investment, system-level requirements and acceptance testing across the larger software enterprises project team, program and portfolio organizational levels. In this whitepaper, we describe a Lean and Scalable Agile Enterprise Requirements Information Model that scales to the full needs of the largest software enterprise, while still providing a quintessentially lean and agile subset for the agile project teams that do most of the work.
